    This is cool, but it will almost definitely never end up in a park, outside of some promotional situations.

    Disney's been doing awesome work with "Living Characters", like a Mickey that moves his mouth or a BB-8 that can roll around. But for various reasons, they never tend to make it into regular usage.

    If you have a few hours over Christmas break and want to watch a 4 hour YouTube video (I promise if you're on HN on a Sunday, you'll be delighted by it), I highly highly recommend this video:

    "Disney's Living Characters: A Broken Promise" by Defunctland https://www.youtube.com/watch?v=NyIgV84fudM

      I watched a bit of this with my 8 year old and he kept asking to come back to it over the week. We watched the entire thing and he kept bringing up interesting thoughts and had good questions. Felt like it was his first “wow this lecture is actually super interesting” experience.

    • peacebeardan hour ago |parent

      It’s not as technically impressive, but my toddler was very impressed by the R2D2 that was making its rounds in the park. Not part of a show; you could go right up to it. Probably the only character where the theme park robot is really indistinguishable from the real thing.

    • this_user6 hours ago |parent

      A lot of it just seems to be marketing. Present the shiny new toy, get the news headlines, people book their stays, and then it doesn't really matter if they ever actually make it into the parks.

      • makeitdouble3 hours ago |parent

        We're probably looking at a halo effect ?

        Similar to concept car demoed at trade shows, we get an idea of Disney's technical engagement, and some of it will perhaps in some way or form get applied into future products/attractions.

      • gkoberger6 hours ago |parent

        Eh, maybe. I have a less myopic view... I think their Imagineers just like pushing the envelope, and there's a difference between awesome tech vs things that can withstand the wear-and-tear of millions of guests.

        Nothing about all that tech makes me think Olaf could withstand a hug from an excited kid.

        Disney does a ton of R&D that doesn't directly make it into the parks, such as smokeless fireworks (they donated the patent for this) and their holotile floor (basically an endless VR room you can walk around). I imagine they don't know the practicality at the start, like any good R&D.

          In the video, one of the presenters removes and reattaches Olaf's nose. The robot laughs and loves it. I thought to myself, how many kids tearing at that wear item will this survive? I think the answer is significantly less than the thousands of kids who are expected to see this attraction every day.

            Idk about that. It is just a plastic part with magnets in it. Sounds like it would be easy to replace on a regular basis.

            I would be a lot more concerned about kids tripping the robot over if they are allowed to interact with the robot that closely.

        • hamdingers4 hours ago |parent

          Each time they trot out one of these new robots they strongly imply, if not outright promise, that they will become part of the parks[1], that's the problem. Things like HoloTile are accurately marketed which makes me believe it's a choice they're making with the character robots.

          1. The article states "he’s soon making his debut at Disney parks," which is misleading to a casual reader who may not realize that Olaf will only appear on the day of his debut.

      4 hours is an awfully big investment... Especially for those of us with multiple young kids and who no longer own their own free time. Care to give the gist?

      • Melonai6 hours ago |parent

        Defunctland is genuinely amazing and always a fun watch, and I never regret the time spent on their videos, they're kind of like a special occasion... though they're getting incredibly long... :)

        There are a few older shorter videos in the half hour range, I highly recommend checking them out if you find some quiet time! (It's awfully hard for me too in recent times, I haven't gotten around to watch the Living Characters one myself, so I can't give the gist... I'm just glad I got the holidays off to finally catch up!)

        • gkoberger6 hours ago |parent

          For anyone who DOES have time, this one is amazing: it combines broadcast history, Disney Channel nostalgia, and a genuinely beautiful storyline.

            and for anyone with 4 hours to kill... here's as an incredible documentary covering the misaligned incentives and poor guest experience at the now-shuttered Disney Star Wars hotel.

            https://youtube.com/watch?v=T0CpOYZZZW4

            She covers everything - the line getting in to the hotel, the size + cost of the rooms in comparison with the same size/cost on a Disney cruise ship, and theories on why the experience was so poor.

              Jenny Nicholsen is as excellent as Kevin Perjurer’s Defunctland. I highly recommend both.

      • crooked-v4 hours ago |parent

        One of the key reasons is that it would be really, really easy to accidentally injure parkgoers with any design big enough to interact with and engineered well enough to be reliable in a full day of appearances.

        For example, the working WALL-E robot that's made a handful of PR appearances weighs seven hundred pounds. They absolutely can't risk that ever running across some kid's foot.

        • luqtas2 hours ago |parent

          > They absolutely can't risk that ever running across some kid's foot.

          imagine it packing a kid into cube

      • gkoberger6 hours ago |parent

        The basic gist is that while the tech is cool, it just ends up being impractical for regular use in the parks. (But like the other poster mentioned, with Defunctland it's less about the tldr and more about the journey and fascinating segues he takes)

        Totally get it's difficult to make time with kids, but depending on your kids ages... the video shows a LOT of Disney characters talking and doing things and the videos are colorful, so it could work as something you can listen to and they won't mind having play in the background!

    • efnxan hour ago |parent

      That bot is cute, but every kid is going to kick it over. Its not realistic to have in a park.

    • jfoster4 hours ago |parent

      They literally sell BB-8 toys that can roll around and say on the blog that the Olaf robot is coming to Disneyland Paris and special appearances at Disneyland Hong Kong.

      • gkoberger4 hours ago |parent

        I know there’s BB-8 toys, but I’m talking about the version meant for the parks: https://youtu.be/RDgZjdZsc6g

        Much like Olaf (and many before him… dinosaurs, WALL-E, talking characters, etc), it was implied he’d wander around the parks. But it tends to happen for a short amount of time, mostly for events, and fade away quickly. (The blog post even says that: Olaf will be part of a 15 minute temporary show, and then will visit Hong Kong).

        Maybe I’m wrong, but I’ve seen this exact thing happen a dozen times over the past 20+ years. (And watch the video I posted if you want to see more!)

        • mrandish3 hours ago |parent

          > But it tends to happen for a short amount of time, mostly for events

          I expect you're correct. While it's fantastic tech, it's also very expensive to keep highly-precise, carefully calibrated micro-machinery like this aligned and operating 12+ hours a day outdoors where temps vary from 50-110 degrees. Disney thinks in total cost of operation per hour and per customer-served.

          While there's probably little that's more magical for a kid than coming across an expressively alive-seeming automaton operating in a free-form, uncontrolled environment, the cost is really high per audience member. Once there are 25 people crowded around, no new kid can see what all the commotion is about. That's why these kind of high-operating cost things tend to be found in stage and ride contexts, where the audience-served per peak hour can be in the hundreds or thousands. For outdoor free-form environments, the reality is it's still more economically viable to put humans in costumes. Especially when every high-end animatronic needs to always be accompanied by several human minders anyway.

          • Animatsan hour ago |parent

            > the cost is really high per audience member.

            Disney has problems with that. Their Galactic Starcruiser themed hotel experience cost more to the customer than a cruise on a real cruise ship, and Disney was still losing money on it. The cost merely to visit their parks is now too high for most Americans.

            It's really hard to make money in mass market location-based entertainment. There have been many attempts, from flight simulators to escape rooms. Throughput is just too low, so cost per customer is too high.

            A little mobile robot connected to an LLM chatbot, though - that's not too hard today. Probably coming to a mall near you soon. Many stores already have inventory bots cruising around. They're mobile bases with a tall column of cameras which scan the shelves.[2] There's no reason they can't also answer questions about what's where in the store. They do know the inventory.

          while I haven't seen them at parks (I just don't make it to any), I have seen them at Star Wars events at my local MiLB team - BB-8 in the size of your video, somewhat interactive and autonomous, same with R2D2. there's usually a human nearby to monitor it, but they're definitely around.

      • ohyoutravel4 hours ago |parent

        R2D2 is an example of one that you can buy in the gift shop (for $20k!) that was promised to make it into the park but just comes out highly supervised, occasionally.

      Why do you say this? I don't have 4 hours right now and would appreciate a TLDR.

      • jen203 hours ago |parent

        I worked with someone who had previously worked on park robotics, and apparently they had to guarantee that the character could not injure a child to be able to put them in parks - a particularly high barrier to actually doing so.

        • conductr3 hours ago |parent

          One look at Olaf's hands alone make that an impossible thing to guarantee. Those stick fingers will eventually poke a kid in the eye if kids are allowed to get close to the character. If they gave him a small intimate stage, or roped off area, to do some act or crowd work that would be more ideal/less risky.

      > We already live in the world where hackers are pwning refrigerators, I can't wait for prompt injection attacks on animatronic cartoon characters.

      It's not necessarily AI controlling the communication. Disney has long had 'puppet' characters whose communication is controlled by a human behind the scenes.

      • crooked-v4 hours ago |parent

        They're already using similar tech for the Mickey meet and greets and the Galaxy's Edge stormtroopers. The details aren't public, but it seems to be a mix of complex dialogue trees with interrupts or context switches, controlled in real time by the actor or operator.

        • yjftsjthsd-h2 hours ago |parent

          That's interesting; if you're doing human in the loop, I would have thought it'd be easier to just do voice swapping. Or did the technology not quite line up?

          • pfychan hour ago |parent

            Someones linked in this thread the Defunctland video essay on these characters that I highly recommend watching since it goes into this in detail.

            But the main reason is, there's a lot of brand imagery on the line with these interactions, someone putting on a voice, or using a voice changer could make a mistake. Disney instead have a conversation tree with pre-recorded voice lines that a remote operator can control. Much harder to mess up

            • dotancohen31 minutes ago |parent

              And possibly more importantly, much easier to keep doing for hours on end. There's no need for a highly trained actor.

    Sometimes the idea of a killer cyborg with a hulking physique and Austrian accent seems absurd. And then we realize the most advanced robots will be made by entertainment companies.

    • dotancohen28 minutes ago |parent

      Arguably entertainment requires a much larger range of precision actions that the robot must be able to accomplish, while being in a less controlled environment. That's the cutting edge.

      Arguably men are two legged walking robots, and men have seams. Even nature couldn't avoid it.

    He looks nothing like a snowman. Snow doesn't look fuzzy. This project appears to focus more on trying to get it moving around in an animated way than getting the character to look right, at least when viewed from photographs.
